404 14TH ST BASE FILE 2024-12-09

The Director may establish Best Management Practices (BMPs) for particular groups of users. These BMPs may include, but are not limited to types or methods of pretreatment technology to be used, methods of source control, minimum maintenance requirements, dragout prevention practices, spill prevention practices, or other requirements as deemed necessary. The Director may establish BMPs in lieu of numerical limits for non-categorical users. When required by the Director, an engineering report as required by, and complying with, WAC 173-240, including detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City for review, and shall be acceptable to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the City under the provisions of this ordinance. Within ninety (90) days after the completion of the wastewater pretreatment facility, the discharger shall furnish as built drawings and its operations and maintenance procedures. Any subsequent significant changes in the pretreatment facility or method of operation shall be reported to and approved by the Director prior to the initiation of the changes. New sources, and new users determined to be Significant Industrial Users (SIU's) must have pretreatment facilities installed and operating, if required, prior to discharge. B. Grease Control/Pretreatment: Measures to control, recycle, remove or pretreat for grease that are applicable to food service establishments, other than SIUs, are subject to the Grease Control Ordinance, #XXXXXXXXX. C. Other Interceptors: Dischargers who operate automatic and coin-operated laundries, car washes, filling stations, commercial garages or similar businesses having any type of washing facilities (including pressure washing and steam cleaning) or any other dischargers producing grit, sand, oils, lint, or other materials which have the potential of causing partial or complete obstruction of the building side sewer or other areas in the POTW shall, upon order of the Director, install approved interceptors, oil/water separators, or tanks in accordance with specifications adopted by the City of Everett such that excessive amounts of oil, sand and inert solids are effectively prevented from entering the POTW. D. Installation and Maintenance: All grease interceptors, oil/water separators, settling tanks and grit traps shall be properly installed, maintained and operated by the discharger at his own expense. The installation shall be kept in continuous operation at all times, and shall be maintained to provide efficient operation. 20
